Well, from my point of view, I'd definitely promote this thing, If I was a point contact "fighter".

Actually, having shotokan experience, I see a lot of use in this. I'd even say maybe more than boxing/MT etc.

One touch, one kill* can finally be real : ))
*Metaphorically speaking.

Stun guns don't really incapacitate with a touch. In the instructions on them, they say that could take up to 7 seconds (!) of continuous contact. I've been stun-gunned by one of the cops I train with, and a quick touch definitely gets you on your toes, but not out. But its difficult to hold it on someone continuously, because their body will instinctively jump away from it with spinal reflexes that are very fast.

IMO, the most fool-proof way to incapacitate someone with a stun gun is to get a bodylock (from the front or rear) and use both hands to pull them close/press the stun gun into them, then fire as needed. This is actually best done with a conventionally shaped stun gun, not the knuckle kind. This seems like one of the high percentage ways of keeping many seconds of continuous contact while they may be thrashing to get away, and the underhook position should be able to neutralize any attacks that might come up. You're also in a good position where you could even put them on the ground nicely when they're out, instead of letting them fall from a standing position where they might hit their head on the ground or something.
